Statement from NSF director on Event Horizon Telescope
This week, the Event Horizon Telescope (EHT) begins a 10-day attempt to capture the image of the supermassive black hole at the center of the Milky Way galaxy. The EHT derives its extreme magnifying power by connecting widely spaced radio dishes across the globe into an Earth-sized, virtual telescope. The National Science Foundation (NSF) has been a longtime supporter of the EHT program, which is receiving a considerable boost in sensitivity and resolution through inclusion of the NSF-funded Atacama Large Millimeter/submillimeter Array (ALMA), located in Chile, into the EHT world-wide virtual telescope. NSF Director France Córdova issued the following statement to mark the occasion: Read more
Scientists believe they are on the verge of obtaining the first ever picture of a black hole. They have built an Earth-sized "virtual telescope" by linking a large array of radio receivers - from the South Pole, to Hawaii, to the Americas and Europe. There is optimism that observations to be conducted during 5-14 April could finally deliver the long-sought prize. Read more
Earth-sized telescope expands to the South Pole to see black holes in detail
Astronomers building an Earth-sized virtual telescope capable of photographing the event horizon of the black hole at the center of our Milky Way have extended their instrument to include the University of Chicago-built South Pole Telescope. The South Pole Telescope, situated at the National Science Foundation's Amendsen-Scott South Pole Station, now is part of the largest virtual telescope ever built- the Event Horizon Telescope. By combining telescopes across the Earth, the Event Horizon Telescope will take the first detailed pictures of black holes. Read more
Astronomers successfully measure the radius of a black hole
An international team, led by researchers at MIT's Haystack Observatory, has for the first time measured the radius of a black hole at the center of a distant galaxy - the closest distance at which matter can approach before being irretrievably pulled into the black hole. The scientists linked together radio dishes in Hawaii, Arizona and California to create a telescope array called the 'Event Horizon Telescope' (EHT) that can see details 2,000 times finer than what is visible to the Hubble Space Telescope.

Mt. Graham telescope to take first-ever picture of a black hole
On Wednesday, scientists worldwide are hoping to take the first-even picture of the black hole believed to be at the center of our galaxy, and the University of Arizona's telescope on Mount Graham will be taking part. The Event Horizon Telescope is a massive "virtual" telescope that will combine 50 radio telescopes from around the world to snap an image of the giant, but distant, black hole suspected to sit at the center of our Milky Way Galaxy, according to a news release from the UA.
